ID the present paper, the authors attempt to deal with the problem of dividing the zoogeographical regions of the greater part of Ghinghai and Kansu Provinces on the basis of their studies of the mammalian fauna of the said region.The zoogeographical division is made from the lowest basic categories, proposed by A. P. Kuzjaken ( 1954), i.e., from groups (biocenoses) of facies and groups of landscapes upwards to the zoogeographical provinces. The principles for dividing groups of facies and those of landscapes have been discussed and may be illustrated in maps. It is pointed out that this system may best be applied to mountainous regions, as in such regions the altitudinal changes of the landscapes as far more striking than the horizontal changes.With 21 groups of facies and 13 groups of landscapes as basic categories, the authors divide the region surveyed into 8 zoogeographical provinces. The present system of dividing of zoogeographical regions is made after E. V. Camoilov's suggestion (CawofljioB, 1957) in combining the eco-geographical types (groups) with geographical regions (provinces).
